I like Weez's idea, but just to twist it a little and sort of combine it with Franco's suggestion, how about doing something similar with altered wrestling quotes?
"One of our members won a gold medal with a broken freaking neck!"
"The best forum there is, the best forum there was..."
"We found the Nacho Man."
"Talk about your psalms, talk about John 3:16... preferably wrestling though."
"With a tear in my eye... this is the greatest wrestling forum out there."
"We lie, we cheat, we discuss wrestling"
I just woke up so these probably aren't that great, but you get the idea.
At the very least, change "smarking out" to something else, that just sounds really nerdy but I do like the idea of rotating slogans.
